facett-graph — crate card

Reverse-engineered (from source — verify, don't trust the name)

• One-line pitch: The graph (node/edge) viewer component on facett-core — build a Scene from a labelled edge list and draw it.
• Does: Provides scene_from_labeled_edges (rows of (src_id, dst_id, src_label, dst_label) → a coloured Scene, ids deduped, nodes FNV-hashed by label) and GraphView (a Scene + Layout, implements Facet with free state_json). Also ships depgraph with DepGraphView/DepNode/DepEdge and draw_arrow — a layered/toposorted dependency-DAG view with deps/dependents drill-down.
• Key deps: facett-core (Scene, Facet, draw, hash_color, Theme), egui, serde_json.
• Shape: lib; small (lib.rs + depgraph.rs).
• Observed role in the workspace: Consumed by facett-arrow (Arrow→Scene→GraphView), facett-pipeline (composes DepGraphView for layout), and re-exported by the umbrella facett. The reusable "graph from edges" adapter korp's Graph and Pipelines views want.

• Primary consumer(s):
• Why it exists (vs the obvious alternative):
• Hard constraint (airgap / no-C-deps / no-FFI / pure-Rust / etc.):
• Release cadence & independence (rides a parent? own repo someday?):
• Status (production / prototype / experimental / stubbed):
• Must-NOT-change invariant:
• Biggest known gap or TODO:
• Anything a newcomer would get wrong about it:
